>             Project: Hive
>          Issue Type: Bug
>          Components: HCatalog
>    Affects Versions: 2.2.0
>            Reporter: Mithun Radhakrishnan

> Map/Reduce jobs that use HCatalog APIs to write to Hive tables using Dynamic partitioning
are expected to call the following API methods:
> # {{HCatOutputFormat.setOutput()}} to indicate which table/partitions to write to. This
call populates the {{OutputJobInfo}} with details fetched from the Metastore.
> # {{HCatOutputFormat.setSchema()}} to indicate the output-schema for the data being written.
> It is a common mistake to invoke {{HCatOUtputFormat.setSchema()}} as follows:
> {code:java}
> HCatOutputFormat.setSchema(conf, HCatOutputFormat.getTableSchema(conf));
> {code}
> Unfortunately, {{getTableSchema()}} returns only the record-schema, not the entire table's
schema. We'll need a better API for use in M/R jobs to get the complete table-schema.
